e claims. (ci. zoe-2) invention relates to acid containers, that is to say, to receptacles which vare adapted to contain corrosive liquids such as acids and the like, whereby the same may be dispensed from 5 time to time as required. f

Numerous attempts have been made to provide a satisfactory container for hydrofluoric acid and the like, whereby the same may be conveniently used in laundries and other establishments for the elimination of rust spots and other ,discolorations which respond to treatment by such materials.

Recourse has been had to the\use of hard rubber receptacles, which, however, are dangerous in that no'matter how carefully they are protected by surrounding casings, the hard rubber shells are quite likely to be fractured and thus permit the escape of the contents. Wax and paraflin shells have also been employed, but

these are even more objectionable for the same reason, and also because of the dilculty of mounting the nozzlesr or other fittings. Containers of sheet metal with thin rubber linings have also been used, which necessitated the cementing of the lining tothe walls of the container, and also involved complications in the attachment of the fittings.

The principal object of the present invention 'is to provide a contaner for highly corrosive liquids such as hydrofluoric acid, which will be simple and inexpensive, yet eflicient for its intended purpose.

A further object of the invention is to provide a container of the character aforesaid which will be so constructed and arranged that it may be quickly and conveniently filled, but which may have a dispensin'gnozzle or fitting readily attached thereto.

A further object of the invention is to provide 40 a container of the character aforesaid which will be both leak and fracture proof.

A further object of the invention is to provide a container of the character aforesaid which may be safely used even by those who do not fully appreciate the dangerous character of the material contained therein.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure l is a vertical central sectional view of an acid container embodying the main features `f the present invention;

Fig. 2 1s a perspective view of the internal portion of the container, certain parts/connected thereto also being shown;

Fig. 3 is a perspective view of a part of a4 protective casing constituting a portion of the structure; and .f5

Fig. 4 is a similar view of other parts thereof. It will, of course, be understood that the description and drawing herein contained are illustrative merely, and that various modications and changes may be made in the structure disl0' closed without departing from-the spirit of the- The internal rubber shell I0 is mounted in an open ended tube II, preferably made of cardboard or the like, the internal dimensions of which are substantially equal to, or preferably slightly less than, those of the internal shell Il). 25

Surrounding the tube II are upper and lower tubular members I2 and I3, respectively, also preferably made of card ard or the like, which telescope over the tube tl a d meet intermediate the ends of said tube, as at I 4, when the struc- 30 ture is assembled.

The lower outer tube I3 is provided with an l end closure member I5, preferably made of sheet metal or the like, having its edge portions formed to engage and grip the lower end of said tube l,\3, 35 as at I6. The upper outer tube I2 is also provided with a similar end closure member I1, also preferably made of sheet metal or the like, and having its edge portions formed togengage and grip the upper end of said tube I2, as at I8. 40 The upper end closure member Il is`provided with a central aperture I9, through which extends a nozzle which will be hereinafter described.

A disk 20 of hard rubber or the like is secured 45 to the inner face of the upper horizontal wall of the internal soft rubber shell I0. This disk 20 has a central aperture 2l, provided with screw threads for the mountingon the shell I0 of a hard rubber nozzle member 22, the under face 50 of which is adapted to compress a portion of the upper horizontal wall of the shell I0 against the disk 20 when said nozzle is screwed in place in said disk, thereby insuring a seal at the place of connection ofthe nozzle member 22 to the 55 inner shell I0. 1f desired, rubber cement may be used between the under face of the nozzle member 22 and the upper face of the horizontal wall of the shell I0, which will serve to prevent the nozzle member from being improperly detached fromthe shell.

The nozzle member 22 may be provided with a central passageway 23 for the dispensing of the liquid therethrough, preferably having at one place a constricted portion 24 which will prevent the material from escaping too rapidly through the outlet. The discharge port 23 may be closed by means of azsuitably threaded plug 25 andwasher 26.

The nozzle member 22 is preferably provided witha iiange 21, which is adapted to be seated or conned'between the upper horizontal wall of the softrubber shell Ill, and the portion of the end closure member I1 which surrounds the central aperture I9 thereof.

The material may be placed within*`- the soft rubber shell I0, which has the hard rubber disk 20 secured on the inner face of the top horizontal wall thereof, before the nozzle member 22 is/mounted on said shell by being threaded in the hard rubber disk 2l).` After the material is placed in the shell I0, the nozzle member 22 may then be inserted and screwed tightly to position, preferably being cemented in place -by means of rubber cement.

'Ihe lled shell IG, with the nozzle member 22 in place as aforesaid, is then finserted in the 4inner cardboard tube II, which, desired, may

' have previouslybeen inserted in\'4 e lower outer cardboard tube I3, and secured `thereto by glue or other suitableadhesive. -The' upper outer tube I2 mayA now be" pla'ced over the inner cardboard tube II, and also secured thereto by glue or other suitable adhesive, this tube I2 being pushed to a-.position where the lower edge thereof abuts against the upper edge of the lower i When it is desired to use the material, it is merely necessary to remove the closure plug 25 and invert the container, whereupon a suicient quantity of the liquid will pass through the constricted passageway 2l, thence through the main passageway, to the outer surface of the end portion of the nozzle member 22, by means of which it may be applied to the goods to be treated. i I

A container constructed as aforesaid will be safe under conditions usually met in the use of such materials as hydroiiuoric acid and the like,

.in that there will be no likelihood of vfracture of the same by shock or blows on the -outer casing.

'loV

It will be -seen that the soft rubber shell I0 will readily accommodate itself to any deformation of the casing. and the walls of the shell being of suicient thickness to be self -sustaining be no likelihood f its rotating within the same when the plug 25 is removed for the purpose of dispensing a quantity of the contents.
